Probability =
(number of ways it can come out the way you want it to)
divided by
(total number of ways it can come out).
Total number of ways it can come out =
number of bottles in the cooler
= (10 + 15 + 13) = 38 .
Number of ways it can come out the way you want it to =
(soda + lemonade)
= (10 + 15) = 25 .
Probability of coming out the way you want it to =
25 / 38 = about 65.8 % .
The rotational order is the number of times it can rotate upon itself.
This means the shape has 9 sides.
360 /9 = 40 degrees
30% times 450 = 135
450 - 135 = 315
